Question 980751

the parabola  intersect the {{{y}}} axis at the point ({{{0}}},{{{y}}})

so, set {{{x=0}}} and solve for {{{y}}}

{{{ y=x^2-5x+4}}}
{{{ y=0^2-5*0+4}}}
{{{ y=4}}}

the parabola intersect the {{{y}}} axis at the point ({{{0}}},{{{4}}})


{{{ graph( 600, 600, -10, 10, -10, 10,x^2-5x+4) }}}
